Just the vehicle for a record track performance? (4-2)
I believe the answer is:
pick-up
'performance?' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps there's a link between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for pick-up that I've seen before include "Improve, increase" , "Recover" , "Small low-sided truck" , "Small truck or lady met informally" , "Collect; casually acquire" .)
